Re: 1/4 Scale Salto
Tape the joint on the underside works well.

Mine has a cup hook in each tail plane with a elastic band between the two going through the fuselage.

Re: 1/4 Scale Salto
Any thoughts on a 1.5mm bar instead of the 2mm ? (with corresponding thinner box, yes, there would need to be some packing adjustment)Peter Balcombe wrote: ↑13 Jul 2020, 12:08 With the outstanding lower rear spar inserted to complete the basic framework, attention turns to the joiner assembly.
This is made up using interleaved brass tubes and 3mm spacers, epoxied together to form a solid block as shown.
Note that the joiner assembly needs to be cleaned up to reduce its overall thickness to that of the joiner tubes (16mm) as it will be a very neat fit between the spars at the outer end, so any thicker & the upper spar will not sit down correctly.
Gliders are out of stock of 15x2 / 16mm box, but I've located some 15x1.5 / 16mm box ...
(I note my Pik 20 uses a single 15mm bar with its wider wings!)

Re: 1/4 Scale Salto
Marc,
I would think that if the material is a similar carbon steel, then 2 x 1.5mm blades would probably be ok as I think the 2 x 2mm are possibly a bit of overkill.
I used twin blades & what I hope is a strong wing to stand up to the spirited aerobatic manoeuvres that a Salto might be put through.
I would think it best to put any spacer between the 2 blades to make the joiner area the same width as I think this will help structurally.
Maybe any ex-structural engineers may like to comment?

Re: 1/4 Scale Salto
Thanks for your previous answers Peter!
Another day... another question!
Did you stick with 0.4mm ply and glass or did you go with the suggestion of 0.6mm or the drawn 0.8mm sheeting for the wings?
Did you add any carbon to the spar ?
TIA!
Marc
